Description: 测试gabor反褶程序
地震信号是非平稳信号，其子波是随时间变化的。Gabor反褶积技术地震道切成若干个Gabor 片，在每一片中子波是不变的，因此可以实现将非平稳信号向平稳信号的转换。因此，Gabor反褶积被认为是高分辨率、真振幅反射系数的估计方法。-Test gabor deconvolution procedure
Seismic signal non-stationary signals, the wavelet is changing with time. Gabor deconvolution of seismic traces cut into several pieces Gabor in each sub-wave film is constant, it is possible to achieve a non-stationary signal to smooth signal conversion. Therefore, Gabor deconvolution is considered to be a high-resolution, true-amplitude reflection coefficient estimation method. Platform: |

Description: he Gabor expansion, which maps the time domain signal into the joint time and frequency domain, has long been recognized as a very useful tool in signal processing. Its applications, however, were limited due to the difficulties associated with selecting the Gabor coefficients. Because timeshifted and frequency-modulated elementary functions in general do not constitute an orthogonal basis, the selections of the Gabor coefficient are not unique. Platform: |
